In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: Which PC operating environment sold more from Microsoft? Passage:Due to the sales growth of IBM clones in the '90s, they became the industry standard for business and home use. This growth was augmented by the introduction of Microsoft's Windows 3.0 operating environment in 1990, and followed by Windows 3.1 in 1992 and the Windows 95 operating system in 1995. The Macintosh was sent into a period of decline by these developments coupled with Apple's own inability to come up with a successor to the Macintosh operating system, and by 1996 Apple was almost bankrupt. In December 1996 Apple bought NeXT and in what has been described as a "reverse takeover", Steve Jobs returned to Apple in 1997. The NeXT purchase and Jobs' return brought Apple back to profitability, first with the release of Mac OS 8, a major new version of the operating system for Macintosh computers, and then with the PowerMac G3 and iMac computers for the professional and home markets. The iMac was notable for its transparent bondi blue casing in an ergonomic shape, as well as its discarding of legacy devices such as a floppy drive and serial ports in favor of Ethernet and USB connectivity. The iMac sold several million units and a subsequent model using a different form factor remains in production as of August 2017. In 2001 Mac OS X, the long-awaited "next generation" Mac OS based on the NeXT technologies was finally introduced by Apple, cementing its comeback.

Example Input: Question: Do more people live in Fauntleroy's birth place than the town where he died? Passage:Archibald Magill Fauntleroy (b. in Warrenton, Virginia, 8 July 1837; d. in Staunton, Virginia, 19 June 1886) was a physician. He graduated in medicine at the University of Pennsylvania in 1856, and in 1857 entered the United States Army as assistant surgeon; but, upon the start of the Civil War, he and his brother, a lieutenant in the navy, resigned at the same time with their father, Thomas T. Fauntleroy. He became a surgeon in the Confederate army, and was president of the board for the admission of surgeons, and chief officer on the medical staff of Gen. Joseph E. Johnston, and served with him until the battle of Seven Pines. He was then ordered to build and organize the hospitals at Danville, Virginia, and afterward had charge of the military hospital at Staunton, Virginia, until the war ended. He remained and practised at Staunton after the war, and was for several years superintendent of the lunatic asylum at that place. His contributions to medical literature include papers on potassium bromide, chloral hydrate, the use of chloroform in obstetrical practice, and a “Report upon Advance in Therapeutics,” which was printed in the Transactions of the Virginia Medical Society.

Example Input: Question: Are the two bays that made The Times "Travel" magazine Top 12 best beaches in the world list both in the same country? Passage:The Bristol Channel has some extensive and popular beaches and spectacular scenery, particularly on the coasts of Exmoor and Bideford Bay in North Devon and the Vale of Glamorgan and Gower Peninsula on the Glamorgan coast. The western stretch of Exmoor boasts Hangman cliffs, the highest cliffs in mainland Britain, culminating near Combe Martin in the "Great Hangman", a 1,043 ft (318 m) 'hog-backed' hill with a cliff-face of 820 ft (250 m); its sister cliff the "Little Hangman" has a cliff-face of 716 ft (218 m). On the Gower Peninsula, at its western extremity is the Worms Head, a headland of carboniferous limestone which is approachable on foot at low tide only. The beaches of Gower (at Rhossili, for example) and North Devon, such as Croyde and Woolacombe, win awards for their water quality and setting, as well as being renowned for surfing. In 2004, The Times "Travel" magazine selected Barafundle Bay in Pembrokeshire as one of the twelve best beaches in the world. In 2007, Oxwich Bay made the same magazine's Top 12 best beaches in the world list, and was also selected as Britain's best beach for 2007.
